I have been testing out connman, the alternative connection manager. While testing connman, I had to remove my network manager. I did an

apt-get purge network-manager*

Now, when I reinstalled the network manager and all its dependencies, including network-manager-gnome, I cannot see it on the panel however, the internet is connected through ethernet. I can access the internet on the browser and also connect vpnc through the cli. but the GUI does not recognize it. Any idea how to get the GUI recognize the eth0?

i will defo try this ! thanks in advance

one thing i would like to add here is that, if i do this change, then i will not be able to get internet from the cli. doing ifconfig after this change will only show up the local adapter.

What do you mean? ifconfig shows all the network adapters regardless of it being commented out on the interfaces file.

your suggestion worked out perfectly fine. Please ignore my previous comment. It has brought back my network-manager-gui detection. Also, ifconfig is now showing all the adapters and i can connect to my vpn as well!! A million thanks to you man!!

Glad it worked out for you. I faced this issue when experimenting with minimal installs. Many thanks to the original author of the solution I linked.
